The purpose of the catalytic converter is to change any unburned hydrocarbons into carbon dioxide and water. As engines become less efficient unburned hydrocarbons and often even raw fuel can be sent out the exhaust.
Once unburned hydrocarbons get to the catalytic converter they are oxidized, resulting in the release of quite a bit of heat.
If your catalytic converter is running that hot, you SERIOUSLY need a tune-up and possibly other engine work. The appropriate repairs will help your fuel economy and give you better performance. My name is Michael and I have a 1991 Cadillac Eldorado, 8 cyl. I had a mechanic from work look at my car. He noticed my catalytic converter turning red, so he said, that was my problem. So I towed my car to Meineke, and they put in a brand new converter. It still turned red. So I towed it back to my home and had new spark plugs, new spark plug wires, new pcv valve, new throttle sensor, and replaced both 02 oxygen sensors, front and back. The Catalytic Converter, is still turning red. I saw someone say, it could be the EGR valve, online. So that is what i am going to do next payday, replace that. If anyone, knows what the real problem is, let me know. I keep doing the things i see online here, but so far, the converter is still turning red. I have also paid for 2 dignostic test to find out, and because the test are by reading the information after i hold the OFF and WARMER BUTTON down. I still do not see what the main problem is. Someone please help me find out what is my problem, Thanks

A catalytic converter can turn red in a 1990 Cadillac Seville due to excessive heat, often caused by a malfunctioning engine or fuel system.

Look that is plausable but the real answer is that the engine is dumping raw fuel into the converter (catalytic converter) and burning it inside the converter and this can be dangerous in some cases you can actually have a mini explosion\fire causing a good bit of damage. I hope this is helpful to anyone needing the answer..
